Documents with location attributes for access and storage

ABSTRACT

In electronic document access control, a document controller receives a document access request from an access device. The request is to access an electronic document previously stored in a datastore coupled to the document controller. The request includes a current location of the access device, and the electronic document is associated with an access location attribute. The document controller compares the current location of the access device with the access location attribute associated with the electronic document. In response to a match between the current location and the access location attribute, the document controller sends the electronic document to the access device. In response to no match between the current location and the access location attribute, the document controller does not send the electronic document to the access device.

BACKGROUND OF THE INVENTION Field

This invention relates generally to security, and more specifically, to location-based document for access and storage.

Related Art

Corporate and personal documents often contain confidential or private information. Storage of these documents is usually guarded while access to the documents is also limited to certain locations and persons. It is a common practice that companies and people store printed document in a locked cabinet or a safe, as well as electronic documents in computers within a company premises or at home. Access to these electronic documents is often limited only to within the company office or home.

The emergence of cloud computing is creating new challenges in the way people deal with documents. Companies, large and small, are moving to cloud computing and cloud storage. Individuals are adopting cloud storage and sharing. Cloud networks employ public network, including the Internet, to provide ease of access and storing and to reduce the cost of storage and services. Despite the convenience of cloud computing, risk of theft for data, document and identity create challenges that did not exist with paper documents. Today, it is not uncommon to see news about data theft such as credit card information, medical data, personal identity and other important company or personal documents. Among the theft victims, many of which are renowned companies, health care centers, credit card companies, e-commerce websites, celebrities, and even government agencies.

Many security measures and products in guarding computer and network access exist, although these measures are not effective. For each measure to secure network access, thieves continue find a hole to break in. For each security hole discovered, security professionals need to figure out a measure to plug the hole. It is a cat and mouse situation and a security arms race between the two camps. Unfortunately, the security professionals are the underdogs, and the thieves often have the upper hand.

In addition to the difficulty of plugging security holes, the pursuit and prosecution of the thieves are difficult as they often reside in a foreign land. Local and national laws often prevent the catching of the thieves and sometimes limit the ability to address the security holes.

The challenges lead many corporations and individuals to be unwilling to store confidential documents utilizing cloud computing technology, which is struggling with access security and data theft issues.

For the purposes of this description, a computer usable or computer readable storage medium can be any apparatus that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The medium can be an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system (or apparatus or device) or a propagation medium. Examples of a computer-readable medium include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM), a read-only memory (ROM), a rigid magnetic disk and an optical disk. Current examples of optical disks include compact disk-read only memory (CD-ROM), compact disk-read/write (CD-R′W) and DVD. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.

A data processing system suitable for storing and/or executing program code will include at least one processor coupled directly or indirectly to memory elements through a system bus. The memory elements can include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution.

Input/output or I/O devices (including but not limited to keyboards, displays, point devices, etc.) can be coupled to the system either directly or through intervening 110 controllers.

Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modem and Ethernet cards are just a few of the currently available types of network adapters.
